Abstract-This paper discusses use of Extensible Messaging and Presence Protocol (XMPP) based applications under Low Bandwidth and High Latency conditions. Such conditions usually occur during communication between air-to-air or air-to-distant sea platforms. Considering the type of subject conditions XMPP applications discussed in this paper is mostly applicable to military and defense industry. In terms of XMPP applications IM, chat, message broadcasting, Customizable Forms (CF), archiving and database functionalities can be considered. Conditions of Low Bandwidth and High Latency require existing XMPP and data exchange mechanism to be revised or simplified. Otherwise XMPP communication is delayed or gets interrupted and the purpose of XMPP application is not properly met. This study discusses the use of compression algorithms to tackle this problem. Although quantitative facts are provided and referenced this paper is based on empirical approach and includes qualitative results.Index Terms-XMPP, low bandwidth, high latency.
